ABSTRACT:
A hinge construction particularly for pivotally connecting the housing and cover of an electrical enclosure together is preferably formed integrally as part of the lid and as part of the housing so as not to require separate fasteners or hinge pins, yet the hinge portions on both housing and cover are formed in a straight-draw die casting operation not requiring side cores. The housing includes two outwardly extending appendages, each carrying a laterally extending pin cantilevered in the same direction as the other pin and axially aligned therewith. One pin at its outer end carries an obstruction jutting transversely outwardly therefrom in a predetermined angular orientation. Hinge portions on the cover also include appendages, but in the form of a pair of outwardly lugs with a laterally extending hole in each which is axially aligned with the hole in the other lug. The hole in one of these lugs is of the same profile shape as the obstruction on the one hinge pin so that the cover can be slipped sideways over both pins simultaneously, but only when the cover is at a predetermined angle relative to the housing.
